Samhällsekonomisk värdering av skillnader i luftföroreningar mellan miljöklass 1-diesel och europadiesel: beräkningar utifrån befintliga emissionsprovstudier från 2003–-2008

Lina Jonsson

The Swedish diesel market is dominated by a fuel quality that differs in several aspects from the fuel quality that is used in the rest of Europe. The Swedish fuel quality was introduced in 1991 as a fuel designed to reduce both regulated and unregulated emissions compared to the standard European diesel. Since then the gap between Swedish fuel and the standard European fuel quality has diminished as the European diesel has improved. This study examines the remaining differences in exhaust emissions between the two fuel qualities, and values the difference in emissions using the official Swedish values for air pollutants in the transport sector.

Information on exhaust emissions from heavy duty diesel engines is taken from a literature study. The results show that the use of standard European diesel (EN590) instead of the Swedish fuel quality (MK1) gives rise to extra emissions of nitrogen oxides (NOx) to a value of 10–19 öre (1–2 eurocent) per liter diesel for heavy vehicles meeting Euro IV or V requirements. For vehicles meeting only Euro III requirements the extra emissions of nitrogen oxides are valued to 19–29 öre (2–3 eurocent) per liter diesel. EN590 also gives rise to more emissions of particulate matter (PM). The valuation of particulate matter depends on the size of the population living in the area where the vehicle is driven. For a heavy vehicle meeting Euro IV or V requirements driven in a small town like Laholm the extra emissions from EN590 is valued to a maximum of 5 öre (0,5 eurocent) while the extra emissions from the same vehicle driven in the inner city of Stockholm is valued up to 52 öre (5 eurocent) per liter diesel. For vehicles only meeting Euro III requirements the extra cost from EN590 is even larger.

Over time as old and dirty vehicles are replaced by new vehicles meeting harder emission requirements the advantage of MK1 over EN590 will diminish. For private cars the difference in emissions is also most probably smaller than between the heavy vehicles that are analyzed in this study due to lower emissions per liter diesel.
